To all f,.//w.1t-/zr may concern;

lle it known that l, Joiinv T. lllooiisriy, a citizen of the 1United States, residingn at Kansas City. in the county ot lVyandott-e 5 and State ofv Kansas, have invented certain new and useful liiiprovenients iii Precipitators. ot' which the following;- is a iill, clair, and exact iflescription, such as will enable others skilled in the art to which ity appertaiiis to niahe and use the saine.

The invention relates to precipitators for separatingl the sediment and foreign sul stance troni water theriiio siphoned troni a ani generator and seeks to provid. an in proved" precipitator which iiiav he connected with and receive water through a skuniner contained iii a steain generator for the pur'- pose oli' precipitating` the sediment troni and returningl the water to the. geiic'ator hy theriiio siphon circulation.

lt is essential that preeipitators be. constructed with as iew joints as possible and that these lie perfectly tight. also that the vater he required loftollow a circuitous rente while exposed to the action oli precipitation so that as near as practicallj7 possible all the water will he suhjected to the sei aratingi` action Yt'or an even space ot' time. and soine i'i'ieaiis ot' silv and quickly reiin 'ine' the sediment is verv advantageoiis.

llie present invention sechs to provide lan inii'ii'oveil pi'ecipitator with a single joint inl the hotly.'Y portion, an iiiiproved means ot estahlishiiit a circuit within the, precipitator. and a novel and practical means of discharging the sediment when collected.

with these and other objects in View7 the invention consists iii the 'features ot ini* proved minstruction. shapes. combinations and areal 'teniente oli parts hcreiiiatler set forth illusuaed in the accoiiipanyin;r d awk ings and iiiore particularlyY pointed out in the claims hereunto appended. i

ln the draa'iiigsz-Figure l is a view in elevation ot the iniproved precipitator connected toga steaiii generator and to a shiniiner within the generator, a portion of the hen awaji' to illustrate the is a view ol' the precipiscction. taken on line a-(i i"ig, 2l is an inverted plan view of Citt 0i r l' tine iipper portion oi' the shell of the precijitator. l la plan view o't the lower portion ot the of the sediment reinovini;` cone.

The s eaiii generator l, is ot coiniiion and well ltnowii construction and is shown inerelvv to illustrate the connection and action ot the preeipitator,` the generator being` lii'olteii a wa v Vtor the saine purpose and to show the skiiiiiner 2./ which is no para of the present iiiventioii. The lower section l oli' the precipitator shell has the shape of one hallvl of a sphere. is hollow and .is provided with the radially pro]ectiiii;h flange fl, around the largest diaiiieter thereof` which is the upward facej the latter tace having a recess .3 around the inner ede'e ot' its diaiiieter to receive the gasket t3. ,l'rojectiiigiinwai'dl)Y troni the upwai face ot the shell section Il are three luge. ,ai vi .ich rests the cone T, the latter being' pi'e'l'ei'ahlv riveted to the lugs as shown. Around the section 3 iinniediatel),7 lindern mth the i'lange l are the lugs S iroiii which project downwardly the legs il, upon which rests the entire weight ot' the precipitator and iininediate coiiiiections. llpon the gasket t3 rests 'the upper section l() oi the l'ii'eciiiiitator shell, which is cylindrical and extends upward and is closed at the upper end by a spheneally shaped' head ll integral with the shell, there hein;Y two hulis or bosses l2 and lil projecting in opposite direction from the head, both of which are threaded to receive lengths of pipe to connect to the steaiii generator, the'boss `l2 accoinniodating the iiitalte and the boss Ail the discharge pipes ot' the precipita tor. The. lower end et the shell section l() is provided with the radically projecting` flange lll which is a companion to the llaiig'e l. and bolts l5 pass through both flanges and draw the upper and lower sections oi the shell tight upon the gasket the opposite sides olE the shell siction l@ are pairs et' tlanges 1G each pair heine; just' tar ei'iough apart to allow the dirisioii'plate 1T to slide freely between` the plate being preferablyT ot copper and placed between the flanges as shown and seated and cured in position with iiietzl cenient that will stand water and teniiierature and harden alter the application. the cement not being illustrated because ol" well known properties and usages.

@n the intake side of the division plate 17 is the hatlle plate 1S preflierahliY positioned n lar the upper end et the plate. whilt` near the lower end ol the plate 17 is the hallle plate lll. the plates fitting the division plate and charge side ot' the plate 17.r v

rl`he intake pipe 22 connects from boss 12 to the upper side ot the generator 1 and to the skimmer 2, while the boss 13 connects through the pipe '23 to the generator 1 at Q1 the object being merelj.' to connect from the skimmer near the wat-.fr line in the geni erator to any point low down on the geni erator so that as the water cools passing to and through the precipitator i-t will increase in gravity and enter the generator' through the pipe 24 it being evident that the pressure is constant at equal elevations.

In operation the steam in the generator forces the. water through the skimmer and pipe. to the precipitator where it is slightly cooled and returned to the lgenerator by gravity.

It is well known that the sediment and properties that are injurious to the interior of the generator are separated troni the water as steam is generated and thoseipropertics are carried with the steam to the surface ot' the water within the generator from where they would naturally settle and form inerustations onv the inner surface otl the generator, but the skimmer provides a discharge tor those propertiesI at the point where they are the most numerous and active and they pass to the preeipitator. the pre .ipitator being larger and ot much greate area than the pipes leading thereto or therefrom the Water passes through `it slowly and gives the sediment and objectionable properties time to settle within the spherical lower sect-ion otl shell I troni wherer it is discharged Jfrom time totime by opening the blowot valve Q5, the eone directs the passage otl water or stream along the inner surface ot' the walls ot the cone T and removes the sediment immediately whereas it the cone were not provided .the Water 'or steam would eut a channel down through the center ot' the sediment and leave most ot it in the shell. lt will be understood that it' the blowoll' valve is opened for a moment the water will be discharged from the intake side ot' the shell section l() and steam will be discharged. this often being the result in cleaning the preeipitator. It will also be understood that with steam in the intake side ot the shell 10 enteringthrough the boss 12 this side ot' the shell will be of a much higher temperature than thel side next to boss 13, and these variations of temperatures lwhile without the eone the shell is never cleansed even though the valve 25 is opened until the water or steam shows a clean discharge, the saving in heat units lost by cleaning the shell with the cone being considerable over that which is lost without the aid ot' the cone.

It is obvious that numerous changes .may be made in the arrangement ol parts and connections without departure fromthe essentials of the invention.

lVhat claim as new, and desire to secure by Letters Patent. is:- l

1. ln a preeipitator. a closed cylindrical shell. a division wall extending Jfrom the upper end of said shell downward7 integral lugs extending into lsaid shell below said division wall, a eone whose largest diameter is smaller than the interior otl said shell said eone supported by said lugs,- the vertex ot' said cone projecting upward,'and said vertex being some distance below said division wall.

2. ln a.' precipitator, a closed cylindrical shell. a division wall extending' from the upper end ot' said shell downivard` a Cone rigidly connected to and supported within saidshell, the largest diameter ot said cone being smaller than the interior of said shell the vertex ot' said cone projecting upward and said vertex being some distance below said division wall.
